G-Link System: Intelligent Centralized Actuator Control & Monitoring Solution

In the era of Industry 4.0, managing hundreds of field devices in isolation has become obsolete. G-Link is an advanced communication system that enables real-time data acquisition and remote control of an entire actuator network through a stable and reliable loop architecture.

Key Features of the G-Link System

1. Ultra-Reliable Loop Network Connection

Actuators are interconnected in a tightly integrated loop structure using optical fiber or metallic cables. The advantage of this architecture is ensuring seamless signal flow even if a single point in the loop fails, guaranteeing that monitoring is never interrupted.

2. Large-Scale Management Capability

A single G-Link loop is capable of synchronized management for up to 127 field devices. This is the ideal solution for large-scale plants, helping to optimize signal cabling infrastructure and significantly reduce installation costs.

3. Flexible Interface (Master Station)

The G-Link Master Station acts as the central “brain,” easily communicating with a host computer or DCS through various methods:

• Industrial Communication: Standard Modbus (RS-232) protocol.

• Digital Signals (DI/DO): Open/Close control and status feedback.

• Analog Signals (AI/AO): Precise real-time monitoring of valve opening degrees.

Core Benefits of Implementing G-Link

• Optimized Centralized Control: The status of every valve in the plant is displayed on a single screen in the control room.

• Instant Monitoring & Early Warning: The system continuously updates valve positions and operational status, immediately sending alerts if fault signals occur to ensure rapid risk mitigation.

• High Communication Durability: Utilizing optical fiber provides absolute electromagnetic interference (EMI) resistance, ensuring data accuracy in harsh factory environments.

Practical Applications

The G-Link system is the top choice for centralized control solutions in:

• Centralized water and wastewater treatment plants.

• Petrochemical refinery complexes and oil storage terminals.

• Power plants and large-scale pulp and paper production lines.
